What to Expect from a Vulnerability Scan

BHIS outlines how automated vulnerability scans (typically using Nessus) serve as a non-destructive "map" for penetration testing, reassuring clients that scans use conservative policies (no DoS or brute-force) and rarely cause outages. The post advises coordinating scope and rules of engagement with testers, tuning scan policies to avoid sensitive devices (printers, SCADA), and treating excessive alerting or fragile devices discovered by scans as security issues to be addressed.
